Application filed August 7, 1911. Serial No. 642,590.

To all whom 2t may concern:

Be it known that I, ALBERT S. HUNTER, S12, a citizen of the United States, and a resident of the city of Quitman, in the county of Brooks and :State of Georgia, have invented certain new and useful Improvements in Machines for Splitting and Removing Stumps, of which the following is a specification. v

My invention relates to improvements in devices for splitting and removing stumps and trees, especially pine stumps from which turpentine is to be extracted, and it consists in the combinations, constructions and arrangements herein described and claimed. 1

An object of my invention is to provide a device by means of which the roots of the and split, and finally the stump itself extracted.v v A further object of my invention is. to

. provide a port-able device which may be easily moved into operating position, andin which the parts are balanced so as to facilitate such movements. y

A further object of my invention is to provide a device having interchangeable tools which will permit double operations such as splitting and cutting.

Other objects and advantages will appear in the following specification, and the novel features. of the device will be particularly pointed out in the appended claim.-

My invention is illustrated inthe accompanying drawings forming part of this application, in which similar reference characters indicate like parts inthe several views, and in 'which:- I

Figure 1 is a side view of the device showing the same in operation, Fig. 2 is a detailed view showing the cutting device, Fig.

3 is a side view of the splitting device, Fig. 4 is an end view of the splitting device, and

Fig. 5 is a reduced plan view of the device.

"In'carrying out my invention I provide a truck .or base portion 1 mounted on wheels 2. A platform 3 is mounted on a circular track 4' carried by the base 1, the platform being arranged to turn on the circular track around the central pivot 5. Mounted on the platform 3 is a support 6 having bearings 7 for an arm 8.'- At one end of this arm is a counterweight 9 and at the opposite end a handle 10. v A circular saw 11 is carried in bearings 12 on the arm 8.

At the opposite end of the platform 3 and disposed in 'such a. position as to counter balance the 'weight of the saw and driver .i'sthe engine E. It is provided with a belt 16 which drives the saw 11. It is also pro vided with a drum 17 wound arope 18 by means of which the we1ght'15 is drawn up. This drum is operated by means of a lever and clutch 19 in the usual.1nanner.

around which is Referring now to Fig. 2, I.'have shown therein a tool T which is especially useful in cutting the roots of stumps. This consists of a curved blade t'which has an'mtegral head t arranged" to enter-and slide between the uprights 14:. The head t -may be attached to the weight 15 by means of a chainv 20. The-splitting devices consist of a blade 8' having a head 8 arranged to enterand slide between the uprights 14. The splitter may also be attached to the weight 15 by a chain 21.

' From the foregoing description of the var rious parts of the device the operation there: of may be readily understood. The device as described is drawn to the place where the stump is to be removed and is then placed in the position shown in Fig. 1 with the con v cave face of the tool T toward the stump.

- The engine is set going and by working the lever 19 the weight 15 may be drawn u and down so as to cause thetool T to split the roots of the stump in 'the manner clearly shown in the figure. In view of the fact that the tool may be shifted from side to side by swinging the platform 3 it will be seen that the-root's may be quickly cut' qr. The saw' is now brought into position and a longitudinal cut through-the center from top to bottom is made. This is done by swing- 'ing the sawdownwardly by means of the handle 10. The saw is then lifted out of the cut and swung one side whilethedriv'erds once more brought over thestump. The splitter S is inserted in the runway between the uprights 14, the lower end of the'split ter being placed-in the. saw kerf in -the stump. -The.driver is then-operated intlie manner alreadydescribed and. the stump is split intwo as shown in'Fig. A. Owing .to

the fact that the roots have", already bee'nvcu t the-stump will readily fall apart. On very large stumps it may be necessary to take another sawe'ut at right angles to the first one, but usually one cut- Will be suflicient.

5 I claim In a stump remoi-ing device, a truck, a platform pivotally mounted thereon, an upright on said platform, an arm pivotally mounted on said upright, one end of said 10 arm being provided with a counterweight, "the other end of the arm being provided With'a handle and having a circular saw mounted thereon for swinging the saw into engagement with the stump, a drop hammer mounted on the platform at the same end with the circular saw, a toolslidably carried by the drop hammer frame and arranged to be broughtinto the initial position of the saw for operating upon the stump roots, and an engine for operating both saw and the drop hammer on the opposite side of said platform, said engine serving as a'counter- Weight for the saw and the drop hammer.
